Carbon Black N220
Functional Fillers & Reinforcing Agents
Carbon Black N220.
BOAO N220 is a premium grade carbon black engineered for superior reinforcement in rubber compounds. With the highest surface area among standard grades (107–121 m²/kg NSA), N220 delivers excellent abrasion resistance, tensile strength, and processing consistency. The fine particle structure provides superior dispersion and uniform distribution in elastomeric matrices, making it ideal for demanding automotive, industrial, and specialty rubber applications. Primary Applications: High-performance tyre treads, automotive rubber compounds, industrial rubber goods, seal compounds Secondary Applications: Wire insulation compounds, hose covers, mechanical rubber goods, specialty elastomer products
